Crassaminicella sp. strain SY095 is an anaerobic mesophilic marine bacterium that was recently isolated from a deep-sea hydrothermal vent on the Southwest Indian Ridge. Here, we present the complete genome sequence of strain SY095. The genome consists of a chromosome of 3,046,753 bp (G + C content of 30.81%) and a plasmid of 36,627 bp (G + C content of 31.29%), encodes 2966 protein, 135 tRNA genes, and 34 rRNA genes. Numerous genes are related to peptide transport, amino acid metabolism, motility, and sporulation. This agrees with the observation that strain SY095 is a spore-forming, motile, and chemoheterotrophic bacterium. Further, the genome harbors multiple prophages that carry all the genes necessary for viral particle synthesis. Some prophages carry additional genes that may be involved in the regulation of sporulation. This is the first reported genome of a bacterium from the genus Crassaminicella, providing insights into the microbial adaptation strategies to the deep-sea hydrothermal vent environment.

克雷萨米氏菌sp。SY095菌株是一种厌氧嗜温性海洋细菌，最近从西南印第安海岭的深海热液喷口中分离出来。在这里，我们介绍了菌株SY095的完整基因组序列。该基因组由3,046,753 bp的染色体（G + C含量为30.81％）和36,627 bp的质粒（G + C含量为31.29％）组成，编码2966个蛋白质，135个tRNA基因和34个rRNA基因。许多基因与肽运输，氨基酸代谢，运动性和孢子形成有关。这与观察到的菌株SY095是形成孢子的，能运动的和趋化营养的细菌相一致。此外，基因组包含多个携带所有病毒颗粒合成必需基因的噬菌体。一些噬菌体携带可能与孢子形成调控有关的其他基因。Crassaminicella，提供有关微生物对深海热液喷口环境的适应策略的见解。
